Centipedes

Vancouver Island, Canada - September 2011

Centipedes are easily distinguished from millipedes by them having only one pair of legs per segment and also the presence of a pair poison claws immediately below the head, which they use for capturing and injecting venom into their prey. Many species, particularly the large, tropical ones, are capable of delivering a painful bite to humans.
